Frequently Asked Questions
What does a Body Control Module do on a Silverado 2500?
The BCM acts as the central computer for your truck’s body electronics. It manages non-engine related functions like interior and exterior lights, power windows, door locks, the security system, wipers, and the HVAC climate control system.

What if my airbag light is on after I install it?
